Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

NASL family Scientific Linux Local Security Checks NASL id SL_20161103_LIBVIRT_ON_SL7_X.NASL description The following packages have been upgraded to a newer upstream version: libvirt (2.0.0). Security Fix(es) : - It was found that the libvirt daemon, when using RBD (RADOS Block Device), leaked private credentials to the process list. A local attacker could use this flaw to perform certain privileged operations within the cluster. (CVE-2015-5160) - A path-traversal flaw was found in the way the libvirt daemon handled filesystem names for storage volumes. A libvirt user with privileges to create storage volumes and without privileges to create and modify domains could possibly use this flaw to escalate their privileges. (CVE-2015-5313) - It was found that setting a VNC password to an empty string in libvirt did not disable all access to the VNC server as documented, instead it allowed access with no authentication required. An attacker could use this flaw to access a VNC server with an empty VNC password without any authentication.

A local attacker could use this flaw to perform certain privileged operations within the cluster. (CVE-2015-5160) * A path-traversal flaw was found in the way the libvirt daemon handled filesystem names for storage volumes. A libvirt user with privileges to create storage volumes and without privileges to create and modify domains could possibly use this flaw to escalate their privileges. (CVE-2015-5313) * It was found that setting a VNC password to an empty string in libvirt did not disable all access to the VNC server as documented, instead it allowed access with no authentication required. An attacker could use this flaw to access a VNC server with an empty VNC password without any authentication.

NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2016-2577.NASL description From Red Hat Security Advisory 2016:2577 : An update for libvirt is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The libvirt library contains a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. The following packages have been upgraded to a newer upstream version: libvirt (2.0.0). (BZ#830971, BZ#1286679) Security Fix(es) : * It was found that the libvirt daemon, when using RBD (RADOS Block Device), leaked private credentials to the process list. A local attacker could use this flaw to perform certain privileged operations within the cluster. (CVE-2015-5160) * A path-traversal flaw was found in the way the libvirt daemon handled filesystem names for storage volumes. A libvirt user with privileges to create storage volumes and without privileges to create and modify domains could possibly use this flaw to escalate their privileges.
